- This PR aims to prevent a buffer overrun issue found in FtwGetLastWriteHeader function.As per the current code, when there is a malformed blocks (with all bytes as 0s) then `Offset += FTW_WRITE_TOTAL_SIZE (FtwHeader->NumberOfWrites, FtwHeader->PrivateDataSize)` would access beyond FtwWorkSpaceSize. - Also added the signature check to validate work space Signed-off-by: Sureshkumar Ponnusamy <sponnusamy@microsoft.com> |
